Why do random rewards work?
Random rewards work because a surprise keeps its pull: dopamine is more responsive to unpredictable rewards than to predictable ones, and behavior rewarded on an unpredictable schedule tends to persist.
What the research shows
Research on reinforcement schedules, going back to B. F. Skinner, found that behavior rewarded on an unpredictable schedule stays steady and tends to persist (Skinner). Brain research explains part of why: dopamine is more responsive to unpredictable rewards than to predictable ones (Schultz 1997).
Informed by research on how good feelings fade with repetition, the app also varies the kind of reward, not just the timing, which helps a reward hold your attention (Sheldon and Lyubomirsky).
What it doesn't show
Much of this research comes from the lab, and no study has tested Rewarding Habits itself. We describe the mechanism the app is built on, not a guaranteed result.
Isn't that how slot machines work?
They share a schedule, not a design. In Rewarding Habits nothing is staked, every completion gets something, and no reward is ever for sale. Researchers flag frequent, variable rewards as a possible ingredient of behavioral addiction (Clark and Zack 2023), which is why we keep rewards honest and never add stakes or near-misses.
In Rewarding Habits
What the app does
Every completion gets something. It might be an ocean moment (Swell, Light gathers, Glass sea, Rain clears, Golden hour, Bioluminescence or The Crest), a quote, or a reward you wrote for yourself. Which one arrives is the surprise. Your own rewards don't come every time; they turn up now and then, when you least expect them.
Rewards are never picked by AI, and the draw happens on your device.
